Paul Krugman is skeptical about the oft-repeated claim that the current high unemployment rate is because the entire economy needs to be reconfigured and workers retrained:

So all the evidence contradicts the claim that we’re mainly suffering from structural unemployment. Why, then, has this claim become so popular?

Part of the answer is that this is what always happens during periods of high unemployment — in part because pundits and analysts believe that declaring the problem deeply rooted, with no easy answers, makes them sound serious.

I’ve been looking at what self-proclaimed experts were saying about unemployment during the Great Depression; it was almost identical to what Very Serious People are saying now. Unemployment cannot be brought down rapidly, declared one 1935 analysis, because the work force is “unadaptable and untrained. It cannot respond to the opportunities which industry may offer.” A few years later, a large defense buildup finally provided a fiscal stimulus adequate to the economy’s needs — and suddenly industry was eager to employ those “unadaptable and untrained” workers.

But now, as then, powerful forces are ideologically opposed to the whole idea of government action on a sufficient scale to jump-start the economy. And that, fundamentally, is why claims that we face huge structural problems have been proliferating: they offer a reason to do nothing about the mass unemployment that is crippling our economy and our society.

So what you need to know is that there is no evidence whatsoever to back these claims. We aren’t suffering from a shortage of needed skills; we’re suffering from a lack of policy resolve. As I said, structural unemployment isn’t a real problem, it’s an excuse — a reason not to act on America’s problems at a time when action is desperately needed.
